Added ability to load data from NMEA log fileAdded ability to filter out NMEA loggins to a more reasonable polling intervalOutput points are colored based comparisys between driven speed and speedlimit

Fixed issue with NMEA parsing on western hemisphereFixed issue with NMEA parsing where interval filter was not properly filtering if there was no valid input within the interval (for example a long time no input when you drive threw a tunnel)Added small black line for visualizing the heading of input points, currently only visualize the selected input point

I added a new function to the test client: "Route sanity check". This function is useful if you want to send xMapmatch results to xRoute and you signal as such a high interval that you cannot use HistoryConsideration (aka global matching). if you do not have HistoryConsideration the chances of xMapmatch picking the wrong result will increase. "Route sanity check" will evaluate the map match result and only send points it is fairly certain of that they are OK to xRoute for a route calculation.
